Which fuel releases the least CO and CO2 emissions among Petrol (Type 1), Diesel (Type 2), Electric-Petrol (Type 8)?

Which fuel releases the least CO and CO2 emissions among Petrol (Type 1), Diesel (Type 2), Electric-Petrol (Type 8)?

• A. Petrol (Type 1)
• B. Diesel (Type 2)
• C. Electric-Petrol (Type 8)
• D. Hybrid

Answer: (C)

Electric propulsion tends to have the fewest exhaust emissions because there is no combustion of fuel producing CO and CO2 while the vehicle is running on electricity. An Electric-Petrol system can run on electric power for much of its operation, reducing or eliminating tailpipe emissions compared with petrol or diesel engines. Petrol and diesel vehicles burn fossil fuels and release CO and CO2 from the exhaust, while a hybrid still uses the petrol or diesel engine at times, so its emissions aren’t as low as an electric-driven mode. In summary, using electricity to power the vehicle minimizes direct emissions, making Electric-Petrol the lowest-emission option in this context.
